DAB Smart Press on/off Auto Reset Controller 1.5 & 3hp
SMART PRESS is an ON/OFF electronic device designed to switch the pump ON/OFF without using an expansion vessel. The device protects the pump against dry running without using level probes or float switch.
All the SMART PRESS models have a MANUAL AND AUTOMATIC RESTART.
Smart Press is an automatic electronic device, designed to regulate pump operation, without using autoclave tanks.
Smart Press performs the following operations:
1) Controls pump operation, automatically and without interruption, with constant pressure and delivery during supply from one or more distribution points.
The pump starts when the pressure of the system is less than the fixed pressure (std 1.5 bar). Il stops when Smart Press no longer detects an appreciable outlet flow (see point 2).
2) Keeps the pump operating for a brief period (approximately 5 seconds) after supply has stopped at the tap closing.
3) If there is no water at the suction point, it blocks the pump,without using level probes or float switches. Or it releases automatically when a pressure above the one required to start the motor-driven pump is injected in the delivery line.
